28 STALK-EYED CRUSTACEA 



2. Euprognatha gracilipes. 



Eiiprognatha gracilipcs . A. Milne Edwards. 



The carapace is slightly flattened. The median and 

 branchial spines are short ; the spines on the lateral edges 

 are well developed ; the surface is granular. The horns 

 composing the rostrum are short, and the spine from the 

 interantennulary partition is not visible on a dorsal view; 

 consequently there appears to be only four spines forming 

 the rostrum. The basal joint of the external antenna; 

 has below two longitudinal series of toothed granulations 

 forming two crests, one inside and one outside this 

 joint. 



The external maxillipedes are granular, and the sternal 

 plastron has granular ridges. There are fine granulations 

 on the legs. 



The first pair of walking legs, in the male, is long and 

 thin ; shorter in the female. Below the insertion of each 

 leg there is a flat granular expansion of the sternum. 

 These prolongations border the carapace in its postero- 

 lateral part, and resemble a series of teeth. 



Range. — Dominica, Barbados, Santa Cruz ; in deep 

 water. 



3. Euprognatha inermis. 



EiiprognatJia ineniiis . A. Milne Edwards. 



The median and branchial spines of the other species 

 are represented by elevations. The granulations are well 

 marked. The rostrum appears to be composed of four 

 spines, the interantcnnular spine not being visible on a 

 dorsal view. 



Range. — Guadaloupe, the Grenadines ; in deep water.
